To show these results in a more general manner, we have computed the
average escape times for 40000 combinations of energies
\(E\in [0.21,0.25]\)  and noise intensities \(\xi \in [10^{-7},10^{-2}]\) .
To visualize the result we have used in Fig. REF , a
color-coded map in which hot colors indicate high average escape
times. As we could also observe in Fig. REF , this
color-coded map shows that the value of \(\xi _t\)  increases with the
energy, at the same time that the intensity of the trapping is reduced. This implies that if the energy is increased to values deep in the fully chaotic regime, the effect of the trapping in the average escape times might be negligible. In this situation the traditional mechanism of trapping [1]}, based on a reduction of the escape rate due to the blurring of the natural measure of the system, is expected to dominate the trapping phenomenon of the particles in the scattering region.
